The CCTV on the train captures two people trying to get out of the path of the oncoming train

As the train continues into the tunnel, as it takes three quarters of a mile for a train to stop, two people can be seen scurrying to the side of the passageway.

Miraculously they escape with some scratches and bruises from the terrifying moment on the tracks running alongside Downhill Beach in Co Derry, Northern Ireland.

Translink released the footage today to raise awareness of the dangers of wandering onto train lines.

Mark Atkinson, head of civil engineering at Translink told Belfast Live: “Our trains travel at speeds of up to 90 miles per hour and if a driver has to apply the emergency brakes, it will take two thirds of a mile for the train to stop.

“In other words, not even the fastest athlete on the planet could outrun a train.

"The network can look like a handy shortcut or a good place to place, but the risks are just not worth it.

"Aside from the very obvious risks to life and wellbeing associated with trespass, every time we receive reports of pedestrians on the rail network, we have to apply a ‘caution’ or speed restriction of 5 mph to trains operating in the area until we are assured that the area is clear."
